Blackmagic s Resolve for Mac can be an easy and fast solution to create color corrected or just delogged dailies. The available workflows include the possibility to use 3D-LUTs on all shots or different LUTs on single shots, primary grading with the possibility to export a CDL plus a full DI secondary grading environment. MXF/DNxHD files generated by the ALEXA are supported within Resolve from Version A basic knowledge and understanding of the software DaVinci Resolve is a must for the described workflow below. If you have never used Resolve before, please refer to the Getting Started section of the DaVinci Resolve Manual. ALEXA Dailies using Resolve 9 Workflow Guideline Page 2 of 10

4 The ALEXA Reel-Name Naming convention The ALEXA camera records both ProRes and DNxHD files in the following naming-convention: filename - camera index/unit - reel counter - clip index - clip counter - shooting date yyyymmdd - unique camera ID Reel-Name The file header holds the Reel-Name of each shot. For our example file mentioned above this would be: A001R1K4 Reel-Name The Reel-Name is generated from the camera index, reel counter and camera ID. To keep the Reel- Name in any render generated from Resolve we need to tell Resolve where to find the Reel-Name. Go to the Master Project Settings page and scroll to the bottom. Please activate the following option in the Conform Options : Assist using reel numbers from the: and choose the sub-option Embedding in source clip file. After this option has been selected all ALEXA ProRes and DNxHD files will import with the correct Reel-Name as seen in the screen grab on the next page.

5 Applying 3D-LUTs to your timeline To convert all your shots from Log C to Video color space you need to apply a 3D-LUT. DaVinci Resolve 9 already ships with the standard ALEXA Rec709 LUT named Arri Alexa LogC to Rec709. For all other LUTs regarding the ALEXA camera, please go to our online LUT Generator using the following link: Please download 3D-LUTs in the DaVinci Resolve format. While ProRes and DNxHD is legal range encoded, the LUTs are applied to RGB images in the software and these are full range. So please download LUTs as following for Log C to Rec709 conversion: Source: Log C - Full Range Destination: Video - Full Range ColorSpace Rec 709 Scaling Photometric Video This will result in a 3D-LUT named: ALEXA_K1S1_LogC2Video_Rec709_EE_davinci3d.cube ALEXA Dailies using Resolve 9 Workflow Guideline Page 5 of 10

6 Place the LUT in Resolves LUT folder: /Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT/Arri To activate newly importet LUTs go to the Look Up Tables page in your Project Settings and press the Update Lists button. If you want to grade your dailies in LogC color space you should load the LUT in the 3D Output Lookup Table section. This will first apply your grading to the image and second the 3D-LUT. If you prefer to grade in video color space use the LUT in 3D Input Lookup Table. This will first apply the 3D-LUT to your image and second your grading.

7 Rendering your footage for editing Open the DELIVER page and activate the following options: First please choose your rendering format. A good balance between file size and image quality for editing is ProRes Proxy for Final Cut Pro or DNxHD 36 for AVID Media Composer, which gives you very small files in full HD resolution. Later in the project you can relink or conform to the original camera files and get the best possible image quality for grading. Next activate the following settings: Render timeline as: Individual source clips Use source filename Use Commercial Workflow: Place reels in separate folders This will keep the naming of your render files consistent to the original files and will render each Reel into a separate directory.

8 Resizing 2k ProRes files for a DCP finish Re-format 2K 16:9 to 1.85:1 US Widescreen DCP (cropped) Create a new timeline with a frame size of 1998 x 1080 pixels. In the project settings, make sure that the Input Scaling Preset is set to Center crop with no resizing. All clips added to the sequence will automatically be center-cropped to the 1.85:1 aspect ratio with the correct field of view. The individual clips can be reframed by moving them within the sequence frame. Re-format 2K 16:9 (flat) to 2.39 Widescreen Create a new timeline with a frame size of 2048 x 858 pixels. In the project settings, make sure that the Input Scaling Preset is set to Center crop with no resizing. All clips added to the sequence will automatically be center-cropped to the 2.39:1 aspect ratio with the correct field of view. The individual clips can be reframed by moving them within the sequence frame. Re-format 2K 4:3 anamorphic to 2.39 Widescreen Create a new timeline with a frame size of 2048 x 858 pixels. In the project settings, make sure that the Input Scaling Preset is set to Center crop with no resizing. All clips added to the sequence will be center-cropped to the 2.39:1 aspect ratio, but without being desqueezed. Create an Input Sizing Format Preset and scale the image to times width and times height. Select the clips in the timeline and apply the preset to show them in the correct aspect ratio and filed of view. The individual clips can be re-framed by moving them within the sequence frame.

9 Creating EDLs to conform original footage With Resolve you can conform Final Cut Pro XML or AVID AAF files. Most often EDLs are still used in an offline/online workflow. Therefore we provide all necessary information regarding ALEXA files in this section. For conforming Final Cut Pro XML and AVID AAF please refer to the Resolve User Guide. AVID Media Composer 5.0 Editing ProRes/DNxHD files in Avid Media Composer differs from editing in Final Cut Pro in terms of Quicktime Header metadata. The Reel-Name is not imported from the ProRes/DNxHD files using AMA, but can be easily added into any EDL using the method below: Open your sequences in the AVID EDL Manager (version and higher) and use following configuration in the options menu. EDL Type: CMX 3600 In Master List menu > Reel ID Type: Tape or File Name In Options menu >Tape name truncation: Remove Middle In Comment menu > choose: Source File (original file name) Example: 001 A001R1K4 V C 01:00:18:00 01:00:18:05 01:00:00:00 01:00:00:05 * FROM CLIP NAME: SHOT_003 * SOURCE FILE: The EDL example includes all necessary metadata of the original ProRes/DNxHD file to conform by: Tape Name Source Time Code Original File Name ALEXA Dailies using Resolve 9 Workflow Guideline Page 9 of 10

10 Final Cut Pro To export an EDL from your sequence in Final Cut Pro, please choose the Menu Item File -> Export -> EDL. In the dialog choose the following options: Example: TITLE: CUT01 FCM: NON-DROP FRAME 001 A001R1K4 V C 01:00:18:00 01:00:18:05 01:00:00:00 01:00:00:05 * FROM CLIP NAME: The EDL example includes all necessary metadata of the original ProRes/DNxHD file to conform by: Tape Name Source Time Code Original File Name Contact In case you have questions or recommendations, please contact the Digital Workflow Solutions group within ARRI via digitalworkflow@arri.de.
